New InfiniBand Architecture Specification Scheduled for Release at SC12

After an extensive review process, Release 1.3 of Volume 2 of the InfiniBand Architecture Specification has been approved by our Electro-Mechanical Working Group (EWG). The specification is undergoing final review by the full InfiniBand Trade Association (IBTA) membership and was available for vendors at Plugfest 22, which took place October 15-26 at the University of New Hampshire Interoperability Lab in Durham, New Hampshire.

All IBTA working groups and individual members had several weeks to review and comment on the specification, and we are looking forward to the official release at SC12, taking place November 10-16 in Salt Lake City, Utah.

The Importance of a Fast Supercomputer Highway

This month, Appro published a blog post on the importance of moving large data sets quickly in supercomputing, which featured InfiniBand as a main driver of speed in the high performance computing space. The article noted that InfiniBand’s extensive range of features improves productivity and performance, making it a staple on the TOP500 list of the world's most powerful supercomputers.

“To say the speed of InfiniBand technology has improved over the years may be a vast understatement. The solutions could deliver speeds of 10 Gb per second when they first hit the market in 2002. Current components are capable of clocking in at 56 Gb per second, improving every three years to meet the performance demands of high performance computing users and applications”

As we head into Supercomputing 2012, we look forward to seeing the TOP500 list again this year. To read the full Appro blog post on InfiniBand’s use in HPC, visit the Appro blog.


The IBTA and OpenFabrics Alliance (OFA) will be sharing a booth at the upcoming supercomputing convention. Be sure to check back on the IBTA’s website to learn more about the wide variety of InfiniBand and HPC-related topics being discussed at SC12.

Swing by and visit the IBTA and OFA at SC12 booth #3630 to partake in conversations with industry experts. Topics will include:

  • The IBTA Integrators list
  • Hardware testing and interoperability
  • Quality assurance capabilities for software
  • Hand’s on cluster tour
  • Globus Online with RDMA
  • Achieving low latency in virtualized cloud environments
  • IBTA specification Vol 2 v1.3
  • High speed optical connectivity
  • Utilizing high-speed interconnects for HPC

Supercomputing experts, including Bill Boas, Cray, Katharine Schmidtke, Finisar, Alan Brenner, IBM, Todd Wilde, Mellanox, Rupert Dance, Software Forge and Josh Simons, VMware will be in the booth to answer your questions and present on topics currently affecting the HPC community.

IBTA and OFA members will also participate in a panel discussion on Exascale and Big Data I/O, taking place Wednesday, November 14 at 1:30 p.m. Mountain Time. The panel, moderated by Bill Boas with the IBTA will discuss the drivers for future I/O architectures and whether they should be open or proprietary. Panelists will consist of IBTA and OFA member companies representing three major components for HPC clusters: systems, fabrics/networks, and storage.

Don’t forget to check the SC12 website to learn more about Supercomputing, and stay tuned to the IBTA website and Twitter to follow IBTA’s plans and activities at SC12. See you there!
